AT&T S5 on tmobile compatibility - AT&T Samsung Galaxy S 5

Just a quick question,
I received a galaxy s5 for work today and it is the att version, if I unlock it and use it on tmobile, does it support the same bands as the regular tmobile branded one?? Like LTE and hspa+ 21.
Thanks for all your help ahead of time and tend apologize if this has been posted before, I tried looking for something similar but was not able to find anything.

I have a AT&T Galaxy S5 unlocked. I put my friend's T-Mobile sim card in it and everything worked even LTE without changing anything (APN), it changed automatically. My brother has Claro (by the way I'm in Puerto Rico), with that one I had to change apn's manually to get data working.

I'm freed my AT&T S5 for use on T-Mobile last month and it works just fine. Didn't have to modify any APN settings either as the phone was able to pull it off the T-Mobile SIM.

In all freq's? AWS as well?
SAMSUNG-SM-G900A, with 128gb SD & Rooted.

That's what I'm wondering. I know LTE will work fine. But what about AWS and hspa.

Switching between Note and other ATT (LTE) phone?

Is anyone switching between the Note and an ATT LTE phone? I deleted the APN's that were there and added the same ones from the Note. I'm not in an LTE area anyways. Will this work? Will ATT recognize my device and do some kind of provisioning that might mess things up when I go back to the Note? All is good once I put the correct APN in. I just wonder if ATT will provision it and then it not work because it's looking for that 4g LTE plan APN.

4G LTE not active

I have an unlocked Galaxy S4 active i9295 and I cannot get the 4G or the LTE working since I do not have even the option I only have WCDMA/GSM I travel around the world with this phone and now I am in Ireland on 3 and still I am getting H+ showing and not LTE or 4G. Is there a way to activate 4G or is there any special 4G sims ?
I would check your APN settings, seeing how you are unlocked, the proper APN may not be installed to match your Sim, check with your carrier, to make sure they are 4G and LTE capable and get their settings.

Try ShowServiceMode. It should help to unlock LTE band. It worked for me here in Poland, because local career's LTE was locked by my Russian firmware. But using this program I can only switch between phone calls (GSM/3G) and LTE, they cannot work simultaneously.
Thank you guys. One major thing is that why I can even see the option in the settings? If anyone else has some information please help out.
Thanks

[Q] Sim Unlocked At&t s5, will it work with Verizon's network?

I carrier unlocked my Galaxy S 5 and wanted to know if it would work on Verizon's network.
It might work on Wcdma, & Lte. Maybe other chime in.

I'd like to know as well.
Because I'm switching and my S5 is carrier unlocked.
When I put my VZW SIM (which works fine in an iphone 6) in the phone there is no indication of a problem, i.e. wrong sim, etc.
However the signal icon is generic and if I try to place a call it gives me that dreaded not registered on network pop up.
If I look in the properties on the phone the (VZW) number is displayed but it does not show as activated on network.
So my question is does the S5 (actually purchased at a Best Buy store as MetroPCS and unlocked to use on ATT) have the proper modem to work with VZW? If not I will need to sell it.
Interestingly enough I put the ATT SIM in the (VZW) iphone and it worked instantly. Placed calls, send SMS, and get LTE speeds with nothing to change whatsoever!
Here's a fairly good read on network bands and compatibility between carriers....
It should help.....g

Can my unlocked T-Mobile G6 work on my Verizon network???

I recently bought a supposedly unlocked T-Mobile LG G6, but somehow my Verizon SIM card isn't working on it. The previous owner installed the T-Mobile unlock app and successfully unlocked it, so I'm really just not understanding what's going on. I tried to do a factory reset and restart the phone with my new SIM, tried to unlock it again (it says it's already permanently unlocked), etc. Help/advice would be much appreciated!!
is the VZW sim card already activated?
did you try using TMO sim card and see if its working with that?
try with LTE only mode with VZW.
Your tmobile branded G6 might not have all the CDMA bands to work with Verizon.
Verizon still uses CDMA.
If the phone is really unlocked, it will work on AT&T, Crickett, T-Mobile and most GSM networks.

Mi 9 cant activate with LTE on AT&T network?

So I got a Chinese edition phone with band 2, 4, 5, 12, and 17 to fully support both TMobile and ATT network. The Global edition was missing band 17 for ATT so I didnt want to go that route. Been going back and forth with ATT a bit for the past few days since my device came in. The phone shows up and an "unknown device" on their network when we tried adding the IEMI. It will get UMTS (2g) and HSPA+ (3Gish/4G), but will not connect to any LTE or GSM. The phone supports GSM fine, so its strange that it wont do normal cellular connection over that, it will only do cellular over UMTS. The device wont detect as an LTE device and so the sim wont activate LTE on it.
Anyone else with ATT have this issue? And were you able to resolve it somehow?
Or those with TMobile in the US, are you able to activate the phone fine and get full coverage and LTE working?
I messed around with the connection settings in the *#*#4636#*#* menu. Only the "LTE/TD-SCDMA/UMTS" and "LTE/TD-SCDMA/WCDMA" will work properly at all. Both options give me UMTS for cellular, and HSPA+ for data. Of the 4 APNs that ATT uses, only the "ATT Phone" will work at all. The standard LTE APN "NXTGENPHONE" will leave the phone with no data or cellular service. This is related to the phone not being detected as an LTE device and the SIM not activating as such.
I simply put my AT&T sim in my China version and it worked straightaway. I didn't have to do anything else.
I am on Cricket, which leases service from AT&T, so I should know if it works once it comes Tuesday.
Just for perspective, I got a EU version of the Mi 9. Popped in a T-Mobile sim and it worked out of the box. Try the other sim slot. Could be your sim card if not.
Try these codes in Dialer. See if that helps anything.
VoLTE *#*#86583#*#*
VoWIFI *#*#869434#*#*
I was just making an ATT account so no previous activations or sims. So that could be the issue. I will try activating a sim with an old phone and then move the sim over. Or since it is the same hardware as a Galaxy S10, ill see if I can find a store that will activate a sim with a floor model S10 and then let me swap the sim into my Mi 9
Straight talk (ATT sim) lte without issue. no programming necessary , I have the global model though

Where did you guys buy the China version from?
US mobile white SIM from starter kit (T-Mobile) works well with LTE on Chinese model of Mi 9. Black one (Verizon) technically works, registers in the network and enables data, but Verizon refuses the IMEI as non-certified brand of the phone. Trick with activation on the iphone first and switching to xiaomi did not work, service gets cut off, when trying to make a call, it keeps dropping. AT&T based: Cricket and Straight Talk work just fine too.

Thanks for the info.
I was wondering about Verizon, since it support some CDMA bands and support 2 out of 3 of the LTE bands they use (doesnt support B13). Unfortunately I never tried it myself since half the coverage near me uses the band this phone doesnt support on Verizon.
I went and got my ATT account updated to an old Nexus 6 IMEI number and it got LTE on the N6. I then took the sim and put it in my Mi 9 and now the Mi 9 has LTE. So for anyone just getting this phone, you must have an IMEI on your account that is recognized as an LTE phone. If you try to add the IMEI of the Mi9 it is not recognized by ATT and wont provision LTE.
IMEI spoofing does not work with Verizon, as they simply ban the device. They call it “non certified”. Bands are seem ok.

I been purchasing from liaow. Never ran across a issue with them
I've been having the same issue, with a recently-bought (last week arrived) Mi 9 Global on AT&T postpaid. LTE showed up and worked fine day one, now network speeds are dropped down to 3.5G speeds. Anyone else have success with getting LTE on a fresh SIM?
